Some of these rules include mandatory vehicle inspections, strict speed limits, and adherence to hours of service regulations. Commercial drivers must also have a Commercial Driver’s License (CDL) obtained after passing various tests to assess knowledge and skill levels. Commercial drivers need to be aware of the rules of the road, such as yielding to pedestrians, obeying traffic signals, and avoiding distracted driving. Ignoring these rules can have severe consequences, including fines, license suspensions, and even imprisonment in some cases. Furthermore, commercial drivers are subject to stricter blood-alcohol limits and may be required to undergo regular drug and alcohol testing to ensure safety on the road. By following such regulations, commercial drivers can help prevent accidents and injuries while operating their vehicles in Quebec.

To begin your career in commercial driving, you must obtain your Quebec Class 1, Class 2, Class 3, or Class 4 Heavy Vehicle Driver Licence.
These online practice tests were developed to help individuals study for their Heavy Vehicle driver’s licence. Our practice testing area is designed to help you learn the information on your actual written knowledge test and familiarize you with the testing format. All testing material is covered in official Quebec’s ‘Driving a Heavy Vehicle‘ manual.
